Concrete-Grandy Creek KOA

We are thousand trails members, but decided to stay on the KOA side so we could guarantee a pull thru site. Throughout our week there, we only had a few other RVs stay in the KOA side and it was very quiet. The bathrooms and laundry facilities were nice, and the staff members were pleasant. The park was a great base camp for hiking in the cascades. We’ll definitely come back!

Stayed her for 6 nights. Initially only had 3 nights booked. Once getting here I immediately said I wanted to stay longer. I just liked the campground! We checked multiple times to see if we could extend, and finally on Thursday night they a cancellation for Friday and Saturday. I definitely would return here and stay even longer.

This campground is a both a KOA & Thousand Trails Campground. They have designated sites depending on which company you made your reservations through. For RVs they have a variety of sites (back in, pull through, FHU, W/E only). During our stay here the dump station was closed as they were waiting on parts for a repair. As a result they designated a pull through FHU site as a temporary dump station.

Check in is noon and they definitely waited till then. Roads and parking pad in site is gravel. Was a bit unlevel for our class A, so we needed to use blocks under our front tires. Lots of mature trees throughout the park.

Park has a pool & spa, but they were closed for the season. Bathrooms and showers available, along with a laundry room. They do have a fenced in dog area and playground for children. They did offer a few activities for campers on Saturday, including candy bar bingo.

Had decent Verizon signal. Able to talk, text, search internet and stream videos.

Currently there is a burn ban in the area. They only allowed profited and propane cooking.

Nightly fee free with with Thousand Trails membership

Some may really love this place and there isn’t anything blatantly wrong here, but this type of camping is not for me. I generally prefer campgrounds with a little more space and less crowded so take this review for what it’s worth.

My first time at any KOA and honestly I was a little disappointed by how greedy this company is. It seems there was an up charge for everything for example, there is an extra charge for WiFi and they wanted $15 extra to secure a specific site. I generally knew what KOAs are about before booking the site but this was the only campground available in the area on the specific dates I was looking for so I didn’t really have another choice. Way over priced in my opinion. Paid about $55 (with tax and fees) for our little patch of grass with water and electric only. I let them pick my site instead of paying extra to secure the spot i wanted. We have a 22ft class B. Luckily the showers are free and clean, and that’s really all I needed for our two-day visit to North Cascades. Some sites have really great shade but ours, site 57, did not during the heat of the day. Cell service for Verizon was good, not great, but could still stream Netflix after buffering a little while. Our neighbors were really friendly and quiet, however I caught the “dad” sneaking off into the woods directly in front of our site to dump his portable septic tank! I couldn’t believe my eyes. Not once, but twice he did this! I’d had enough at this point and said I wouldn’t be back to any KOA if I didn’t have to. My impression is that generally those who book KOAs have no idea about camping (which is fine, I know everyone starts somewhere) and don’t know campground etiquette. Again, it’s just not my cup of tea but I can see how all the amenities, such as the pool, playground, bouncy blob, etc, would be great for families and beginners.

Grandy Creek KOA / Thousand Trails is located near Concrete Washington just off of North Cascades Highway. Grandy Creek KOA / Thousand Trails is all about location. Conveniently located to Baker Lake, Mount Baker, the Baker-Snoqualmie National Forest, and the North Cascades National Park, Grandy Creek Thousand Trails puts you in easy reach of spectacular scenery, alpine lakes, and world class hiking. We absolutely enjoyed our stay at Grandy Creek Thousand Trails, and we show you why in our video. Verizon cellular service clocked in at 38.9 Mbps download speed and 4.55 Mbps upload speed. AT&T cellular service clocked in at 40.5 Mbps download speed and 0.64 Mbps upload speed. T-Mobile cellular service clocked in at 9.55 Mbps download speed and 2.32 Mbps upload speed.

Gated entrance with phone to call for "ranger" to come check you in. Thousand Trails has a row of sites as well so the signage is a little confusing when you arrive. Definitely unhook your toad even if you have a pull-through as the interior roads are snug.
Lots of tall trees so nice shade but no satellite from our rooftop dish. Dirt and gravel sites with small green grass outdoor space. Picnic table and fire ring. If you keep your blinds open you'll get to know a lot about your neighbors.
We had 50 amp FHUs that all worked fine. They allow tents and additional people at some of the sites so this is a very crowded park. We didn't use the facilities but showerhouses are provided.
We don't site outside a lot anyway so this park was fine and we'll stay here again when in the area.

Beautiful, clean, and spacious campground!

We stayed here three nights with our Thousand Trails membership. We were VERY fortunate to snag the last full-hook up spot on the last pull through row. It was an almost perfectly level spot and came with a nice park table and fire pit (which we didn’t use due to current fire ban).

The laundry facilities are decent. Do check the sign for scheduling as there are specific days/times it can be used due to COVID restrictions.

Overall great experience! We’d love to stay again when in the area.
